Abstract: Articles are blow-molded from a polyphenylene sulfide resin having a melt flow in a range of from about 1 to about 10 g/10 min., and preferably in a range of from about 4 to about 8 g/10 min. When filler materials such as mica are added, the upper end of the acceptable melt flow range is raised to about 15 g/10 min. By maintaining mold temperatures in a range of from about 250 DEG to about 400 DEG F., and preferably from about 275 DEG to about 325 DEG F., the polyphenylene sulfide material in the blow-molded article is provided with a semi-crystalline structure, and is dimensionally stable at temperatures of at least 500 DEG F. Filler materials are preferably provided in a range of from about 10 to about 20 weight percent.
